The DCNEV250 Series 900V 250A High-Voltage DC Contactor Relay is designed for electric vehicle (EV) and eMobility applications, including charging station, battery power supply, DC power control, circuit protection, and other switch control applications. The high-current, high-voltage relay can also be used in uninterruptible power supply and other electronic control systems.

A coil economizer greatly reduces coil power and heating after the contactor is energized. Once the contactor is energized, it takes minimal coil power to keep the contacts closed due to Pulse Width Modulation (PWM) reducing the average power delivered by pulsing the electrical signal.

This 250A relay also features a magnetic arc blowout design that dissipates electrical arc between the contacts within an IP67 sealed, gas-filled arc chamber. This design creates a safe EV contactor that allows higher make/break voltages and no electrical arc leakage.

This model of the DCNEV250 Series high-voltage DC contactor (DCNEV250-GB) features a 48-72V dc coil voltage rating, polarized load terminals, and a single-pole, single-throw (SPST), normally closed (NC) auxiliary contact.
